Title: Improvements in or relating to embroidering machines
IPC: D05C11/16
Filed: 1922-01-05
Abstract: 173,775. Eberhardt, H. Jan. 5, 1921, [Convention date]. Embroidery machines of the Heilmann type, and having revoluble cylindrical take-ups surrounding the needle-clamps, are provided with mechanism for re-threading the needles. The needleclamps N form part of bars 1<c> which are reciprocated by means of a cross-bar 22 and a lever 24 from a rocking-spindle 25, and are intermittently rotated, together with take-up cylinders 12, from a shaft 17. The clamps N can be opened, when in their forward positions, by the withdrawal of keys 4 in the rods 1<c> by means of levers 38 and a rocking- spindle 43. When the thread is being pulled through the fabric by means of the take-up cylinders, guide-rods 44, 51 are moved to the positions shown in Fig. 2 so that the thread is pulled straight, and is wound correctly on the cylinder 12. To remove the thread-ends from the needles a lever 55, Fig. 1, to which are attached bands 56, 57, is rotated so that the needle clamp N is reciprocated through holes 57<a> in the bands; on the return of the clamp, the lever is partly raised, and cutters 58 sever the knotted thread loops. Thread from a spool 94, Fig. 2, passes between tension discs 73, through guide-bars 68, between prongs on a bar 66, and is held in a thread clamp 70 on a bar 67. In the threading operation, the bar 66 is moved longitudinally to the position shown in Fig. 9, and is then turned upright by the longitudinal movement of inclined surfaces on a bar 66b. The bars are then moved to the position shown in Fig. 12. A hook 79, Fig 2, which is actuated by moving a stepped bar 90 now descends through the needle eye, and draws the thread up through the eye. The apparatus is then moved to the position shown in Fig. 13. The opposite clamp pulls the needle and threadend through the thread-loop, and the material to set the knot and winds a thread supply on its cylinder, after which shears 76, 77, mounted on a lever 74, cut the thread, the loose end of which is again held by the clamp 70. Specifioation 173,776 is referred to.
Patent GB-677598-A (GB)
Title: Process for the production of phosphorus sulphochloride
IPC: C01B25/10
Filed: 1951-01-05
Abstract: Phosphorus sulphochloride is prepared by reacting phosphorus trichloride with sulphur in the presence of sulphur monochloride as catalyst.  The reaction proceeds at atmospheric pressure at or below the boiling point of the mixture.  The sulphur monochloride is removed on completion of the reaction by the addition of elemental phosphorus which reacts therewith in known manner to yield sulphur and further phosphorus sulphochloride which can now be removed by distillation.  It is preferable to leave an amount of phosphorus sulphochloride in the distillation residue to act as a solvent and diluent for the residual sulphur since on chlorination, phosphorus trichloride and sulphur monochloride may be formed ready for the next reaction.  Phosphorus can thus be added in elemental form only.

Title: Monitoring equipment
IPC: H03M1/00
Filed: 1958-01-07
Abstract: 878,653. Electrical selective signalling systems. HAGAN CHEMICALS & CONTROLS Inc. Jan. 7, 1958 [Jan. 22, 1957], No. 651/58. Class 40 (1). In a system for indicating the value of a condition being monitored by a transducer having a non-linear characteristic a reference signal is generated which increases non- linearly with time in such a way as to correspond with the non-linear characteristic of the transducer and the time taken for the reference signal to rise from zero to the value being produced by the transducer is measured by counting pulses from an oscillator to thereby provide an indication of the value of the condition being monitored. As described, the reference signal approximates to the non-linear transducer characteristic by increasing linearly over a number of short periods and is produced by an integrator 21, Fig. 1, to which a number of constant potentials are sequentialy applied by a resistance network 105. The reference signal and the signal from the transducer are applied to a comparator 15, at terminals 16 and 14 respectively which maintains a gate 63 open so long as the reference signal is smaller than the signal from the transducer, thereby permitting pulses, from a multivibrator to pass to a counter comprising three multi-cathode tubes 74a, 74b and 74c. The tube 74c-the hundreds tubeis arranged to sequence the resistor network 105 (which produces constant potentials for application to the integrator) and the number registered in the counter is indicated on neon tubes 81. Specifications 829,712 and 878,654 are referred to.

Abstract: 1460400 Diaphragm for alkali metal halide electrolysis MARUZEN OIL CO Ltd 8 Jan 1975 [11 Jan 1974 21 Oct 1974] 750/75 Heading C7B Alkali metal halide solutions are electrolysed in a cell having a diaphragm of a cation exchange resin which comprises an ethylenic hydrocarbon polymer backbone on to which is grafted a side chain derived predominantly from mono- or dihydroxystyrene. The polymer may additionally be sulphonated and/or cross-linked. Grafting is  effected by irradiation of the base polymer with α-, γ-, or x-rays or electrons, during or after which it is contacted with the styrene compound or an equivalent acyloxystyrene and in the latter case is then hydrolysed. From 5-500 wt per cent, based on the backbone polymer, of grafting monomer may be added. Specified backbone polymers are polyethylene, polypropylene, polybutene, polystyrene and its methyl and butyl derivatives, and polyvinyl cyclohexane. Cross-linking agents listed are difunctional compounds reactive with phenolic OH groups (e.g. diepoxides, diisocyanates and acid dihalides); polyenes (e.g. divinylbenzenes); and  organic sulphonic acids. Conventional sulphonation procedures are used to add 0.5-2 sulphonic groups per hydroxystyrene unit. The grafting and cross-linking reactions may be effected simultaneously. The polymer may be treated in film form or prior to film formation. Specified electrolysis conditions are; ferrous cathode; graphite or dimensionally stable anode; temperature 0-90C; a c.d. of 5-30 A/dm<SP>2</SP>; and the optional use of multicompartment cells involving non-selective (e.g. fluorine resin) membranes in addition to the ion-exchange membrane.

Title: Improvements in water cooled rollers
IPC: D06C15/08
Filed: 1964-01-09
Abstract: 980,858. Hollow rollers. E. A. TIMSON. Jan. 9, 1964, No. 963/64. Heading F2U. [Also in Division F4] Relates to a water-cooled hollow roller 1 partly around which is lapped, for cooling, a web P such as paper, cloth, film, foil, such a web, after deposition thereon or application thereto of moisture, inks, stains, dyes, having been heated for drying as by solvent evaporation, polymerization or oxidization. In particular the water-cooled roller is used at the end of a heatset print drying apparatus. According to the invention, such a roller is carried in anti-friction bearings 2 having their inner races mounted on the external roller working surface diameter which is small, say six inches or less, and has extending thereto, for at least half its length, a stationary coldwater supply tube 3 having one or more orifices 4 from which the water may he projected laterally or sprayed. The roller may be free-running. The water is generally centrifuged to line the inner surface of the roller. With sufficient inlet pressure, the sprays or jets continuously penetrate to the inner surface of the roller forcing the hot water already there radially inwards. With roller speeds insufficient for centrifuging, the water builds up and rolls over until the outlet is reached. The orifices 4 may be in one or more straight rows, arranged, if desired, diametrically opposite to neutralize jet reaction and thereby relieve tube bending tendency. As shown, the tube 3 is connected by a union 11 to a supply inlet pipe 10 and coaxially extends through a rotary coupling 8 carried by a fixed bracket 9 and having a stem 8a screwed into an end plate 7 of the roller. At its end remote from the water inlet end, the roller 1 is fully open at 1a to provide a water outlet. The outlet end 1a extends into a spray collection box 12 in which water is caught and led away to waste or to a cooling tower. Flinger fins 13 on the roller end la, or on a short cylinder attached to the roller, promote spray and are interleaved with stationary fins 14 on the spray collection box to prevent water getting back to the adjacent bearing 2. Water getting past the flinger fins may pass down into the spray collection box through a channel 15. Where a series of cooling rollers is arranged following a fast press, a pipe 16 may be provided to exhaust steam from the first roller, and the rollers may be arranged with their inlet ends at alternative sides of the web path, to counteract the greater cooling effect at the inlet ends. For water economy the cooling rollers may feed one to another in cascade fashion and in contra-flow to the web travel direction. In Figs. 2, 3 (not shown) the roller is open at both ends for outlet flow into two fixed receptacles, and a plain fixed inlet water pipe extends coaxially into one open end. A longitudinal scraper blade is fixed to the inlet pipe to ensure that only a thin layer of continuously changing water remains on the inner roller surface in the vicinity of the scraper.
